Hey! Really wanted to play this, but experienced some bugs during the game. I basically drop through ground, or something like that, sometimes dino's legs drop through, and it's legs are spread across the entire map. I'm playing on Mac OSX 10.13.4.
I've recorded a video for you to see, what is happening, althrough, this happens not only on these geyser spots, it can happen at random anywhere.

Hope this'll be fixed, the game looks really sweet, thank you!
